So the other day was my first time using this app and it worked great. Today I open it up, start using the outline tool (as I did the other day) and it just keeps stacking boxes horizontally, so instead of a tree of items branching out downwards, it just goes Level 1 > Level 2 > Level 3 and so on and all the boxes are in one row. I've restarted the program and my computer, and I have no idea why it's doing this... it's Pro 4.1.1

Thanks!
